INCAND ESCENT GAS-BURNER.

SPECIFICATION formingpart of Letters Patent No. 673,303, dated April 30, 1901.

Application filed January 21, 1901. Serial No. 44,164. (No model.)

T0 at whom it may concern.-

Be it known that I, CLARENCE W. TAYLOR, a citizen of the United States, residing at Sioux City, in the county of Woodbury and State of Iowa, have invented new and useful Improvements in Incandescent Gas'Burners, of which the following is a specification.

This invention relates to incandescent gasburners, and has for its object to provide certain improvements therein by which the efficiency of the burner is increased, a higher illuminating power is obtained from a given expenditure of gas, and the term of usefulness or service of the incandesoing mantle is prolonged.

In carrying my invention into efiect I provide novel and simple means whereby heat radiated from the mantle is conducted to a mixing-chamber, where the gas and air are mingled before reaching the point of combustion, means being provided whereby the heat is thoroughly diffused throughout every part of the mixing-chamber and imparted uniformly to the gas and air.

To these ends my invention consists in the features and in the construction, combination, and arrangement of parts hereinafter described, and particularly pointed out in the claims following the description, reference being bad to the accompanying drawings, forming a part of this specification, wherem- Figure 1 is a vertical sectional View of an incandescent gas-burner having my invention applied thereto. Fig. 2 is a detail sectional view of the mixing-chamber, illustrating a slight modification; and Fig. 3 is a detail view of the heat-conductor.

Referring to the drawings, the numeral 1 indicates a tube adapted to be fitted to an ordinary gas-fixture and provided with a valve 2 of ordinary and well-known construction for regulating the quantity of gas supplied to and flowing through said tube. The tube 1 is provided with a plurality of air-openings I 3, and surrounding said openings is a chamber or casing 4, having an annular series of openings 5 in its base or bottom and provided with a rotatable plate 6, having a series of openings 7, corresponding to the openings 5 in the base of the chamber. By turning the plate the openings 5 may be obviously opened or closed to a greater or less extent to regulate the admission of air to the chamber 4, and hence regulate the quantity of air admitted through the openings 3 to the tube 1. The means shown for regulating the admission of air are also of ordinary and well-known construction andform no part of this invention. Arranged on the tube 1 above the chamber 4 is a gallery 8, carrying a chimneysupport 9, and attached to said gallery is a mantle-support 10, from which is suspended an incandescing mantle 11. All the parts above referred to are of known construction and form no part of the present invention, and either or all of said parts may be altered or modified without departing from my invention.

Extending up vertically from the center of the gallery 8 is a tube 12, open at both of its ends and of a very slightly greater diameter than the gas-tube 1. The tube 12 is fitted over the gas-tube and is provided at its upper end with a cylindrical enlargement or casing 13, which constitutes a mixing-chamber communicating at its lower end with the gas-tube 1, which latter terminates at the bottomof the mixing-chamber, and the latter is open at its upper end, as shown. Disposed centrally within the mixing-chamber is a cylindrical heat-conductor 14, formed of any metal which is a good conductor of heat, and said conductor may be hollow, as shown in Fig. 1, or solid, as shown in Fig. 3. I preferably formthe heat-conductor 14 of copper, and the lower end of the same is preferably rounded, as shown, to permit of the easy passage therearound of the air and gas. Upon the conductor 14 at suitable intervals are mounted disks 15, constructed of thin metal or other suitable material or of woven wire. In the former case they are provided with suitable perforations 16, which are so arranged that the perforations of one disk alternate with the perforations in the adjacent disk. If wire-gauze is used, the meshes are so arranged as to break up and thoroughly mingle the ascending currents of gas and air. The disks are shown in Fig. 1 as being dishshaped, the convex side of the same being arranged uppermost; but they may be fiat, as shown in Fig. 2. The disks may be mounted on the heat-conductor in any suitable manner, and as a convenient means for mounting l of a heat-conductor consisting of a centrally them thereon I have shown narrow collars or ferrules l7, slipped on the conductor 14: above and below each disk. The disks are of a diameter approximately corresponding to the inner diameter of the mixing-chamber and operate to hold the conductor 14 in place in said chamber. The upper end of the heatconductor projects a suitable distance above the upper end of the mixing-chamber, as

shown most clearly in Figs. 1 and 2 of the drawings.

Attached to the exterior of the mixingchamber and near the upper end of the latter is an annular flange 18, which at its upper end is offset from the mixing-chamber, as shown in Fig. 1, whereby an annular space is formed between the upper edge of said flange and the upper portion of the mixingchamber. When the mantle 11 is suspended from its support, its lower edge rests in said annular space, thus preventing cold currents of air from entering the mantle between the latter and the mixing-chamber. The flange or guard 18 also operates to prevent currents of cold air from impinging against and breaking, splitting, or disintegrating thelower end of the mantle, whereby the period of usefulness of the mantle is materially lengthened.

The operation of my improved device will be readily understood. Gas is admitted to the tube 1 through the valve 2, and air isadmitted to said tube through the apertures 7, v

5, and 3, the relative proportions of the gas and air admitted to said tube being regulated by the valve 2 and the apertured plate 6in a well-known manner. From the .tube 1 the gas and air passes to the mixing-chamber l3 and through the several disks in said chamher and is ignited as it escapes from the upper end of said chamber around the heat-conductor 14. The conductor 14 is thus heated, and is still further heated by the heat radiated from the mantle 11. The conductor 14 transmits its heat to the disks 15. The air and gas in passing through the disks are thoroughly 'commingled, and the heat from the several disks and from the conductor 14 is thoroughly difiused through every part of the mixing-chamber and uniformly imparted to the gas and air, whereby the mixture of the air and gas is highly heated before it reaches the point of combustion. This, as is well known, gives to the mixture a higher illuminating power and greatly increases the efficiency of the burner.

The exterior of the conductor is preferably roughened for the purpose of causing the'co nductor to more readily absorb heat.

What I claim as my invention is 1. In an incandescent-gas-burner, the combination with an air and gas mixing chamber,

2. In an incandescent gasburner, the com-' bination with a cylindrical air and gas mixing chamber, of a heat-conductor consisting of a cylinder disposed centrally within the air and gas mixing chamber and projecting at its upper end above the .upper end of the mixing-chamber into the interior of the mantle, and aplurali'ty of disks of substantially the same diameter as the interior diameter of the mixing-chamber mounted on-saidconductor and provided wit-h suitable openings for the passage of the air and gas, substantially as described. h

3. In an incandescent gas-burner, the com bination with an air and gas mixing chamber, of a heat-conductor consisting of a cylinder disposed centrally within the air anagas mixing chamber and projecting at its upper end above the upper end of the mixing-chamber into the interior of the mantle, and a plurality of disks mounted on said conductor. and provided with suitable openings for the passage of the air and gas, the tip-per and lower faces of said disks bei'ngrespectivelyc'onvex and concave, substantially as described.

4. In an 'inc'andescen tgas-bu rirer, the combination with an air-andgas mixing chamber, of a heat-conductor consisting of a metallic cylinder disposed centrally within thea-irand gas niixing chamber and projectingabove the latter, said heat-conductor having a roughened exterior, and arranged to be heated by the heat radiated from the mantle, and pl urality of disks mounted on said co-nd uctorand provided with "suitable cps-ma s for the passage-er the air and gas, said disks abutting the interior of the air and gas 'mixingchamber to support'the heat-conductor in place, substantially as described.

5. Inan incandescent gas-burner, the-combi'nation Wuhan-air and gas mixing chamber open atit's upper end'and-provided withmeans for feeding-air and gas thereto, of an annular flange fixed externa'llyon said chamber and forming an annular-space between said flange and chamber for the receptidn of the lower end of themantle, substantially as described. In testimony whereof I have hereunto set my hand in presence'of two subscribing witmisses.
